A new CDC study looks at noise pollution and how much it annoys people and wakes them up at night. The researchers focused on Atlanta and found 9.5 percent of the population is bothered by high noise levels and 2 percent lose sleep over it.

But the U.S. Census found loud traffic noise is worse in many cities, including the D.C. area. So the problem could be more severe here.

Researchers say adequate sleep is as important as eating right and exercising for our health. And more studies across the country are needed to evaluate how much noise pollution is impacting Americans.
